ESPN sideline reporter Wendy Nix: "You've hit more home runs against the Cincinnati Reds than any active player in major league baseball -- I don't know if you knew that. Why is that?"
Berkman: "I don't know. I think it's a statistical anomaly...I think it's just one of those things where everybody has a team that they seem to do better against, and then there are other teams, for whatever reason, you don't do well against, so I can't explain it. I've been asked that several times, but I have no legitimate explanation for it."
The t-test is a statistical test used (among other reasons) to determine, given two samples drawn from normal distributions, whether the two distributions have equal mean. It was developed in 1908 by a chemist working for the Guinness brewery.
